Abstract (en)
An envelope type inner bag body (21) is produced by welding both ends (23a, 23b) of a tubular film (23). An inner bag supply-discharge opening (22) is welded at a position apart from one end portion of the inner bag body by a distance about IW/2 to form an inner bag (20) for a transport tank, which is loaded in a cylindrical tank body (11). When length of the inner bag body is IL, width thereof is IW, inner peripheral length of the transport tank in a longitudinal cross-sectional surface in a longitudinal direction is TLt, and inner peripheral length of the transport tank in a longitudinal cross-sectional surface in a width direction is TLr, IL and IW satisfy the conditions: 0.47·TLt ‰¤ IL ‰¤ 0.6·TLt, and 0.47·TLr ‰¤ IW ‰¤ 0.6·TLr. The envelope type inner bag will be appropriate in size with respect to the transport tank, eliminating the filling failure of the liquid and the breakage of the inner bag.
